Tomato leaf roll is a plant response to some sort of stress. Many possible causes including climate (have no idea what your's is since you don't include your location), over or under watering, poor root development, excess of lack of sufficient nutrients, poorly draining soil, pests such as aphids, etc. etc.

Would need much more info on your growing methods, feeding and watering regimen, the mix used to fill your beds (that has some very strange color to it), climate, etc.to even begin to ID the possible cause. If you are watering daily that alone could be the cause if the plants don't actually need it.

I am located in northern California, just south of the Bay in San Francisco. Our weather is usually mild & fairly consistent. Temps during the day have been 75-85 give or take. The temps do have a tendency to drop quite a bit come nightfall as the coastal fog starts coming inland bringing the temps down to the low 60s, at times in the upper 50s. My soIL has a PH of about 6-6.5. I used chicken manure, some sulfur to bring down the ph, it was at 9, so had to make adjustments. I also added peat moss, as my soIL is a bit on the clay side, it held water & wasnt the best at draining. Its much much better now. I initially had the soil tested & was given recommendations as to how to improve it, I made the corrections prior to planting. The strange color that is seen is not the soil but is mulch, gorilla hair, it's shredded redwood bark. It was what was recomended to me by my local nursery. A side note; All my other tomato plants that I planted at the same time are doing great, it's just the one. I water every 2-3 days dependent on the temperatures & according to the moisture levels that I test frequently. My soIL holds onto water a bit so I'm careful at being consistent. Initially I did have aphids but have eradicated them with use of compost tea which was really effective, there has been no sign of them in almost 2 weeks. There's been no sign of any other pest at all.

Yeah, it's a bit cooler & a bit windy today as it was yesterday. Then last week with the heat wave that hit us.....Lots of extremes going on here.

Yes, resist the temptation to put something on it, just continue with your usual growing practices. Your plant will probably look fine as soon as the weather stabilizes and warms: At least as stable and warm as we get here....Not the best tomato growing area but we do it anyway, right? I wanted to add that along with the rolling leaves, I also had the top tender leaves turn purple. I do get a little panicked but I've grown tomatoes in the same location for several years and both the leaf problems have happened before, the plant grows out of it eventually.

Ohhhhh.....right in the nick of time. Glad I jumped on here. I was just about to mix up some calcium mix & spray away. Thank you very much.

Some varieties are more prone to curling/spooning than others, I can name couple of them like Black Krim and Kumato. Cold weather is also a factor, IMP.

Some of them had that curing early on, but the new growth is normal.

Yeah, we've had some big dips in our temps. We get rather warm during the days 75 to highs in the upper 80s and even the 90s, we have microclimates throughout the region, it gets quite cold when the coastal fog rolls inland, it's a pretty dramatic change in temperature. Today was about 73 tomorrow is expected to be near 90. Trying to grow vegetables with such swinging extremes is proving to be difficult, a week ago we had a heat wave for several days where it was near 100 almost everyday, no fog at night. Normally, It gets cold & windy throughout the nights & stays that way until morning when the sun begins to burn off the fog, then temps climb pretty quick. It's a lot for new plants to handle. Just hope it doesn't cause long term issues. Im a bit of a beginner at vegetable gardening, it's my first time planting tomatoes so I'm a bit overly cautious. I've got Celebrities & Big Beef & Beef Masters, I was told these are hybrids & are resilient, hopefully what I've been told is accurate. Thank you for the feed back.

I believe I've found the culprit.....Initially I had issues with small pink aphids which I used compost tea to eradicate, that type hasnt been back since. However, I went ahead & got some Neem oil, just in case there was another pest that I I wasn't seeing. As soon as I applied, a slew of small white bugs with wings went scattering. I caught one & was able to identify it, they're white flying aphids....I was so focused on looking for the pink ones hiding out under the leaves during the day that I didn't take notice of the white ones landing after sunset when temps cooled down, which explains the leaf curling taking place during the night. Hopefully my tomatoe plants can start recovering now. Thank you all again for your help.
